Answer:
36 people didn't have an umbrella
Step-by-step explanation:
11 minus 7 is 4. 99 divided by 11 is 9. so you multiply 4*9 then get 36
3x +6 = x^2-2x
x^2-5x-6 =0 , which is quardic equation..
solving , we will get, x = 6 or x= -1
hope it helped
Given Data : Length = (7p - 10q) and Breadth = (2p - 9q)
Calculation :
⟹ Perimeter = 2(Length + Breadth)
⟹ Perimeter = 2(7p - 10q + 2p - 9q)
⟹ Perimeter = 2(9p - 19q)
⟹ Perimeter = <em>18p - 38q centimetres</em>
- <u>Answer : 18p - 38q centimetres</u>
